NOTES TO ABSTRACT No. 24.

a The Howe and St.-Vincent ;
of a similar construction to the Nelson. The first, of 2619 35/94 tons, began
building at Chatham in June, 1808, and was launched March 28, 1815 ; the second, of 2612
28/9 4 tons, began building at Plymouth in May, 1810, and was launched March 11,
1815. For the principal dimensions of these ships, and some account of their masts
and yards, see the preceding page.

b One of these was the Isis, first
built as a quarter-decked 50, of 1190 tons, draught-measurement, from the reduced
lines of the late Danish 80-gun ship Christian VII ; as were also the
Salisbury, the single ship, of 1199 tons, in the first " Built" column of
class T in No. 23 Abstract, and the Romney, the single ship of 1227 tons, in
the same column and class of the present abstract. After the Isis had been
constructed, it was thought advisable to cut her in two, and add an additional
port and space to her length ; and also, to take away her poop, forecastle, and
quarterdeck, or at least as much of the latter as reached from forward to about at beam
afore the mizenmast. This made the Isis a flush two-decker, with a short
quarterdeck, or large roundhouse, merely intended as a roof to the captain's apartments,
and increased her measurement to 1321 tons. The number of guns she was to
mount, in her old and in her new state, was the same, 58 ; but the alteration in her
construction gave the Isis nearly a double superiority in force, as the
following statement will show:

According to this, the Isis gained two additional ports of a side
on her first, and three on her second deck, instead of one on each, as had
previously been stated. The fact is, her foremost or bow-port (meant to be vacant) on the
first deck was considered to be sufficiently aft to admit a standing gun, and a
fresh chase-port was cut through further forward. This gave the ship 14 guns of a side on
that deck. With respect to her second deck, the substitution of carronades for long
guns caused the ports to be altered, and admitted them to be nearer together ;
which at once gave the required number.

The second of the two ships in the " Built " column of this class was
the Java, of 1458 tons, constructed from a draught prepared by the surveyors
of the navy, and made a trifle shorter and narrower than the Leander
and Newcastle, but established with precisely the same force in guns and men.

The principal dimensions of the Java were:
